Abstract
Automatic print failure detection and correction are presented. An image is produced on media as it passes through a printer, the image produced by a first print head of the printer. The image is then inspected as it appears on the media for a predefined quality level. When the quality level is unacceptable, remote network notifications can be sent from the printer for proactive maintenance to be performed on the printer. In addition, when the quality level is unacceptable, a copy of the image can be automatically reproduced on an opposite side of the media using a different print head of the printer.
Claims20
A printer, comprising:
- a print head configured to produce a version of an image on a first side of media;
- and
- a capture device situated within the printer to electronically capture and record the version of the image obtained from the first side of the media and configured to verify that a quality level of the version is within a predefined tolerance, the version is electronically captured and verified before the media is dispensed from the printer with the version of the image on the first side of the media.
A printer, comprising:
- a first print head;
- a second print head;
- a scanner;
- and
- an image validation processor, the first print head configured to produce a first version of an image on a first side of media passing through the printer, and the second print head configured to produce a second version of the image on a second side of the media as the media passes through the printer, and the scanner configured to attempt to read the first version of the image and pass results of the attempted read to the image validation processor, the image validation processor configured to compare the results with a threshold value to determine whether the first print head has failed or is in a condition in which failure of the first print head is probable on future prints to other media.
A processor-implemented method programmed in a non-transitory computer-readable medium and executed by a processor embedded in a printer, comprising:
- instructing a print head of a printer to produce a first version of an image on a first side of media passing through the printer in accordance with a print job;
- directing a scanner integrated within the printer to electronically capture the first version of the image as the image appears on the first side of the media;
- acquiring image attributes from the electronically captured version of the image;
- and
- comparing the image attributes against threshold values to determine whether the first version of the image is of an acceptable quality.
